Pushing Docker image to GCP Container Registry times out despite successful auth

Question

I am unable to push built Docker images to GCP Artifact Registry, despite GCP SDK & auth being configured successfully.

This is my GithubActions pipeline setup:

    steps:
      - name: Checkout code
        uses: actions/checkout@v3

      - name: Set up Docker Buildx
        uses: docker/setup-buildx-action@v2

      - uses: google-github-actions/auth@v2
        with:
          credentials_json: ${{ secrets.GCP_SA_KEY }}

      - name: Set up GCP SDK
        uses: google-github-actions/setup-gcloud@v2
        with:
          project_id: ${{ secrets.GCP_PROJECT_ID }}

      - name: Configure Docker to use GCP
        run: gcloud auth configure-docker $CONTAINER_REGISTRY

      - name: Build and Push Docker image
        env:
          SHA_TAG: ${{ github.sha }}
          ENV_TAG: dev
        run: |
          docker build -t $CONTAINER_REGISTRY/$SERVICE_NAME:$SHA_TAG -t $CONTAINER_REGISTRY/$SERVICE_NAME:$ENV_TAG -t $CONTAINER_REGISTRY/$SERVICE_NAME:latest .
          docker push $CONTAINER_REGISTRY/$SERVICE_NAME:$SHA_TAG
          docker push $CONTAINER_REGISTRY/$SERVICE_NAME:$ENV_TAG
          docker push $CONTAINER_REGISTRY/$SERVICE_NAME:latest

As you can see in the screenshots below, all the steps conclude successfully, except the "push" part of the "Build and Push docker image" step:

Not really sure what's the issue here.

Answer 1

You are not using a valid image path to push to, the path has to be of the form

$CONTAINER_REGISTRY/$PROJECT/$REPO/$SERVICE_NAME:$TAG
